Pujiang-1, also known as PJ-1, is a Chinese technology demonstration satellite^[1] designed to promote the construction of smart cities in China.^[4] PJ-1 also monitors weather, traffic and population density of a city. It is the first Chinese satellite that uses 3D printing for the titanium structure of its antenna.^[5] It also features a Wi-Fi router providing a communication network between satellites.^[3]

Launch

PJ-1 was launched on 25 September 2015 at 1:41 UTC from the Jiuquan Satellite Launch Center (JSLC) in China.
